Application filed August 29, 1927. Serial 1%. 216,007.

This invention relates to hinged window sash, and especially to such as swing outwardly.

The objects of the invention are to provide improved adjusting means for such sash, and the combination of such ad ustlng means with special metal frame and sash construction.

The drawings accompanying this application show my preferred construction though modifications within the scope of the appended claims may be made without changing the operation of the invention.

In the drawings Fig. 1 is a sectlonal plan view of a steel window frame and sash hinged to the same and fitted with a brace, all according to my invention.

Fig. 2 is an elevation of the frame and sash as taken through the line 22 of Fig. 1.

Fig. 3 is a bottom view of the sash track plate, Fig. 4 is a longitudinal section of the track plate as seen from the line of Fig. 3, Fig. 5 is a bottom view of the sliding block which fits the sash track,-and Fig. 6 is a side View of the same.

t on of channel or H shaped window frame and sash sections with special bracing or adjusting means positioned within the channel of the section so that the working portions are invisible and protected against the accumulation of dirt. In Fig. 1. the view shows the lower rail or sill 1 of the frame and projecting upward are the two stiles 2 which join the upper lintel (not shown) which is a duplicate of piece 1, and thus forms the complete window frame. The metal section of the frame will be seen to be of a modified H form providing inner and outer channels, the legs of the H section being offset to provide a deep outer flange 3 projecting outwardly and a deep inner flange 4 projecting inwardly, features extending entirely around the frame.

Projecting from the top and bottom of the frame at one side thereof is a pair of hinge brackets 5 (the lower one only being shown) and which are pivotally secured at 10 to a similar pair of brackets or arms 6 (the lower one only being shown) which project from the rangement being such that the sash closes within the window frame with outer flange 9 overlying flange 3 as indicated in the dotted closed position of the sash at X. The sash is glazed on the outside of an inward projection of flange 8 as indicated at 2 1.

Secured within the upturned channel of the frame is a spacing pivot plate 11 to which a fllat brace or adjusting rod 12 is pivoted at The brace rod extends under the lower rail 7 of the sash and is pivotally secured at its end at 14 to a block 15.

Block 15 is slidably mounted in a track plate 16 which fits within the under channel of the lower sash rail and is formed with confrontingly hooked edges 17 overlying the edges of the block, and the track plate is transversely slotted at spaced points as at 18 and with edges turned or curved toward the sash frame so as to form a series of tapered slots across the track plate as best shown in Fig. 4.

The track plate is secured to the under side of the sash frame member 7 by screws 19,

plate and sash frame as shown.

On the outer side of the sliding block 15 i and projecting forwardly therefrom is a fiat spring 21 secured to the block by a screw 22. The forward end of the spring is bent to a wedge shape as at 23 to fit within thewedge shaped slots 18 in the track plate, so that as the block slides along the track through forcible movement of the sash on its hinges, the

spring will yieldingly seat itself successively within the slots, thus steadying the window at diflerent points ofopening.

The particular features of the invention are the special form of the track plate, its mounting within the outwardly or downwardly turned channel of the sash rail so that it is invisible to a person operating the window, and is protected from dirt gathering on the track to grind the guides to destruction.

The spacer 11 fitting within the upward or inward turned channel of the window frame provides a neat rigid construction, in fact all side strain is taken by the channel flanges of both sash and frame, thus relieving the screws and roviding for a simple structure easily assem%led.

I claim: 1 1. In a swinging window mounting, brac- 5 ing means therefor comprising an elongated track plate formed with confrontingly hooked edges, transverse slots in the base of said plate between said edges, a block slidably engaged by said edges, a bracing arm pivoted to it said block, and yielding means on said block adapted to successively engage said slots.

2. In a swinging window mounting, bracing means therefor comprising an elongated track plate formed with confrontingly hooked edges, transverse slots in the base of said plate between said edges, a block slidably engaged b said edges, a bracing arm pivoted to said lock, and yielding means on said block ada ted to successively engage said slots, the p ate adjacent said slots being turned toward the base to provide a wedge form to said slots, and said yielding means formed to fit the Wedge form slots.

WILLIAM DREUSIKE.
